photospheric การใช้

Photospheric magnetism appears to be the primary cause ( 96 % ) of 1996-2013 TSI variation.
Spectral analysis of the star showed that photospheric Si II and He I lines display a simultaneous, periodic variability.
The primary driver of TSI changes on solar rotational and sunspot cycle timescales is the varying photospheric coverage of these radiatively active solar magnetic structures.
A team of astronomers working in the near-infrared announced in 2004, that the more accurate photospheric measurement was 43.33 ?0.04 mas.
Careful radial velocity measurements have made it possible to detect the Rossiter McLaughlin effect, the shifting in photospheric spectral lines caused by the planet occulting a part of the rotating stellar surface.
